Hey! I found this really really cool website a while ago then I just thought, "Hey this really helped me so it will probably help others alot!" It has: Character texture file and folder placement, Stage texture file placement, Stage custom music placement, Boss Textures, Pokemon, Assist Trophies, Other, Character Selection Portraits (CSP's), And Items! It is awesome! I absulutly LOVE it! You should try it out here! (http://brawlhacks.wikia.com/wiki/The_File_Placing_and_Naming_Guide) Isn't it awesome!
Cool, but there are not the Item guide ;) and trophies (NOT ASSIST !!!) guide !
